Title: Ultrasonic image pickup method
Inventor: TODA KOUJI
IPC: G01N29/04
Filed: 1981-10-17
Abstract: PURPOSE:To make the diagonal incidence of sound waves to an object to be examined easy and to permit good observation of the internal part of the object by picking up images by making use of an ultrasonic wave transducer having interdigital electrodes. CONSTITUTION:Interdigital electrodes 3, 4 for inputting and outputting which are spaced from each other are provided to the piezoelectric susbtrate 2 of an ultrasonic wave transducer 1, and are coupled acoustically to an object 6 to be examined through a liquid material 5 such as silicone oil. Now when an AC electric signal is applied to the electrode 3, a longitudinal sound wave L1 propagates in the liquid at an incident angle theta1, and in the place of the object 6 said wave is converted to a bulk wave L2 which enters the inside of said object at an incident angle theta2. The wave reflects on a discontinuous part 6a such as a flaw and is outputted to the electrode 4. If there are no flaws, the wave is reflected on the bottom surface. According to the presence or absence of any flaw, a difference arises in the length of the propagation path and acoustic images are obtained by the different delay outputs. Therefore the diagonal incidence of the sound waves is made easy and the internal images are observed satisfactorily.

Title: Voltage/current converting circuit
Inventor: TANAKA TATSUO
IPC: H03F3/34
Filed: 1987-07-03
Abstract: PURPOSE:To realize high conversion accuracy and low-voltage operation by constituting a voltage follower circuit with high input impedance, and inputting an input voltage to a 1st transistor(TR) for current conversion and also passing it through a current mirror circuit. CONSTITUTION:The input voltage Vin is applied to the uninverted input terminal of a differential amplifier circuit 2 through a protection resistance 1 and the output terminal of the circuit 2 is connected to the inverted input terminal of the circuit 2 to constitute the voltage follower circuit. Further, the base of the 1st TR 3 is connected to the output terminal of the circuit 2, and a current corresponding to the voltage Vin and the value of the resistance 4 is outputted and supplied to the current mirror circuit 7. Consequently, a current which is (n) times as large as the collector current of a 2nd TR 5 is led out as an output current Iout. Then the voltage follower circuit reduces the value of the resistance 4 for current conversion sufficiently because the input impedance is sufficiently high, and there is no influence exerted on the input voltage side even when a large current is led out. Further, the influence of variation in source voltage Vcc is not exerted, so the high conversion accuracy and low- voltage operation are both realized.

Title: Nuclear reactor primary shield wall
Inventor: OCHIAI KATSUJI
IPC: G21C11/02
Filed: 1989-06-29
Abstract: PURPOSE:To minimize the physical quantity of radioactive waste when a primary shield body is disassembled and the quantity of disassembling operation by using reinforcing bars coated with a heat neutron absorber as reinforcing bars at the part of the primary shield wall which is made radioactive. CONSTITUTION:The primary shield wall 7 uses the reinforcing bars 9 coated with the heat neutron absorber 8 as the reinforcing bars 9 in a hatched range 10 nearby nuclear reactor containment 5. The heat neutron absorber 8 is boron or cadomium which is used frequently to control the nuclear reactor and applied to a several mm thickness. Almost none of neutrons which are made into heat neutrons at a concrete part enters the reinforcing bars by the absorption effect of the heat neutron absorber 8. Therefore, the production amount of cobalt -60, iron -55, etc., as radioactive nuclides produced by nuclear reaction on neutrons in the reinforcing bars is reducible nearly to or less than the radiation density of peripheral concrete. Consequently, when the primary shield wall is disassembled, the physical quantity of radioactive waste and the quantity of disassembling operation can be minimized.

Title: Color copying machine
Inventor: KANNO KINYA
IPC: G03G15/01
Filed: 1988-07-04
Abstract: PURPOSE:To eliminate a color ghost and to copy achromatic characters and diagrams easily visible by deciding whether a picture element concerned shows an achromatic character or diagram and correcting a printing signal so as to attain an achromatic color if so. CONSTITUTION:A scanner 1 reads a color image, and a color corrector 2 color- corrects a picture signal 9 according to the color material of a printer 8 to turn into the printing signal 10. A base color removing black board generator 6 turns the printing signal 10 into a 2nd printing signal 11. The picture signal 9 is supplied to a character/picture element discriminator 6, which discriminates whether the picture element concerned shows an achromatic character or diagram to output a character/picture element discriminating signal 14. When the picture element concerned shows an achromatic character or diagram in response to the character/picture element discriminating signal 14, a color corrector 7 does not output 2nd printing signals 11 apart from the black board ones, whereas if not, the 2nd printing signals 1 are outputted as they are, and turn into correcting and printing signal 15. Thus, color ghost is eliminated to copy achromatic character or diagrams easily visible.
